Should I stop being so nervous and just take the test?!?!

As of today, I am officially 50 days late for my period. Yeah, I have not had a period in over 2 months. I took a prego test last month and it said negative. I know that it may have been to early for the hormone to show.. which could result in negative. My BF and I do not wear protection, and I'm not on birth control (yes, ladies I know...) I am ridiculously nervous to take a test. I want to know, but I am so nervous to find out. Like, what if I am? Will I be upset if I'm not? Do I really want to know?! Of course I do.. but UGH Crazy girl thinking over here!! I've had some symptoms.. like nausea, bloating, headaches, lower back pain, and acid reflux and I'm so tired all the time. Some of this is also symptoms of thyroid problems which run in my family.. so I might not even be. I AM SO NERVOUS to take a test... I should probably just stop freaking out and worrying and just take the damn test...... right!
